British musician, singer and presenter Myleene Klass will have an unusual bottle-breaking “assist” from Royal Navy divers when she performs her godmother duties next week by officially naming 113,000-ton Carnival Splendor at Dover Cruise Port.

Petty Officer Christian Rumming, assisted by a Royal Navy dive team led by Lt Ian Richardson, will be underwater near the bow of Carnival Splendor when he will hear a unique radio signal from Klass, playing live classical piano music on the ship’s top Lido Deck. PO Rumming will let out some compressed air from his diving tanks and then climb, in wet suit, safety harness and flippers, a 60ft black marlin ascent rope to reach Carnival Splendor’s name on the top of her bow.

PO Rumming will then break with tradition, for instead of French champagne, he will undertake Klass’s command and smash against the hull a bottle of 1994 vintage Nyetimber English sparkling wine, chosen by Carnival to highlight the British launch its newest ship.

Lt Richardson of the Royal Navy Fleet Diving Squadron said, “This has to be a rather unusual assignment for my men, who are trained in deep sea marine diving and underwater bomb and mine disposal to protect our fleet, but I am confident they can pull this off.”

Carnival Cruise Lines president and CEO Gerry Cahill said, “Myleene Klass and the Royal Navy are a unique combination, and we are very honoured that they are joining forces to successfully name the Carnival Splendor.”

Immediately after being named, Carnival Splendor sets sail for a three-day preview cruise to Amsterdam, returning to Dover on July 13, when it will depart on the same day for its official inaugural 12-day cruise to the Baltic visiting Copenhagen, Warnemunde (Berlin), Helsinki, St Petersburg, Tallinn and Amsterdam.
